Hi!
On kernel 3.17.[23] the SMP seems to be broken. I see messages in dmesg like this:
$this->bbcode_second_pass_code('', '

')
pacman packages that were used: linux-armv7-* and linux-armv7-headers-*
u-boot version used: U-Boot 2014.04 (Oct 04 2014 - 12:34:11) Arch Linux ARM
Same applies to linux-armv7-3.16.3, which I was able to retrieve over http://armrollback.archassault.org/ .
Going back to the old linux-sun7i-3.4.90-5-armv7h kernel everything's back to normal.
Am I doing something wrong or is something wrong?
CU,
